HELP AFM swap to 280zxt

[RUZN]

OK the AFM I got was off a 87 Maxima with a VG30. Issue is.

 

The harness that came on the car has 5 Pins with a Slot for 6.

Now the AFM only has 4 pins?

 

So why did the harness come with 5 pins and the AFM with only 4.. None broken =-)

 

I opened the AFM up and see 4 pins going through to the board all with some tpe of resistor before board and a 5th hole but nothing to board. Now dose this afm have some type of auto clean cycle? or something that it dosent need the 5th and 6th pins?

 

also it was obviously not a Turbo motor. But my ECU is a 1987 Turbo ECU and I have everything else including the chopper wheel so will this swap work with this 4pin NISSAN AFM?

 

THE AFM pins are located on BCDE so A and F are missing.

 

OK went back to wrecker found a oldschool 1986 Maxima with a VG30 and vwala!! 6 Pin MAF with 6 Pin Connector!! yay!! Freebie!!
